Whats a good way to follow up the bomb-teleport without an x-ray?
Divekick/EX divekick, B2 2 if your opponent stays in stand block, NJP (if you expect your opponent to jump towards you), reaction uppercut, and so on. There's a lot of ways you can go about this. You should never Xray out of this setup every single time to begin with, even if you have the meter. As J360 pointed out, this setup won't be effective if you abuse it.
All of Cyber Sub's bomb setups need to be varied enough to keep your opponent guessing. He has no real guaranteed bombs outside of his bomb trap combo, and the glue trap to an extent. When you come out of the teleport after this setup, you should really just wait sometimes to gauge your opponent's reaction to the bomb, and go from there.
Another example of this is Usedforglue's F2 2 1 close bomb setup. You can throw one of these out, and just wait for your opponent to react to it. If they jump back, you can AA them with a divekick/slide, throw a bomb underneath them or freeze/EX freeze. If they jump toward you, you can just uppercut them at peak jump height, then combo it into a slide for 20% (this ONLY works if you catch them at peak jump height, as with Ermac's AA uppercut into teleslam).
You really need to get creative with Cyber Sub to win with him in high level play. You'll never beat a smart opponent if your tactics are linear.
